BACKGROUND Ocular fundus angiography is an indispensable component of the tests utilized for fundus diseases. Dynamic angiography results can provide additional information; however, many difficulties remain. In this study, we introduce a modified method, time-lapse angiography (TLA), to dynamically present imaging results. METHODS TLA, combining time-lapse photography and fundus angiography (using Heidelberg retina angiography II, Germany), includes pre-photographing and post- photosynthesis and ultimately produces a video that is approximately 15 s in length. RESULTS Four typical videos in the article showed the characteristics of TLA, including a short and rapid but continuous and integral presentation, highly valid information, high definition, etc. CONCLUSIONS: TLA is beneficial for the diagnosis of diseases and the assessment of progression and is convenient for peer communication, patient interpretation, and student education. The application of time-lapse photography in ocular fundus angiography is a monumental and innovative attempt.

眼底延时血管造影：一种新的视频血管造影。

背景技术眼底血管造影术是用于眼底疾病的测试中必不可少的组成部分。动态血管造影结果可以提供更多信息；但是，仍然存在许多困难。在这项研究中，我们介绍了一种改进的方法，即延时血管造影（TLA），以动态呈现成像结果。方法TLA结合了延时摄影和眼底血管造影（使用德国海德堡视网膜血管造影II），包括预照相和光合作用，最终产生约15 s的视频。结果文章中的四个典型视频展示了TLA的特征，包括简短，快速但连续而完整的演示，高度有效的信息，高清晰度等。结论：TLA有助于疾病的诊断和进展的评估，并且便于同伴交流，患者解释和学生教育。延时摄影在眼底血管造影中的应用是一项巨大的创新尝试。
